This is a non-exhaustive listing of former bus interchanges or terminals that were once part of Singapore's bus system, and decommissioned due to geographical retention or the introduction of new town centres, or creation of consolidated transportation hubs. Former bus interchanges Woodlands Woodlands Bus Interchange is a former bus interchange that was located at Woodlands Town Centre. Initially planned in the late 1970s as part of a bus service improvement scheme, the interchange started operations in 1981, and had 17 berths. The announcement to build the North-South Line MRT extension and the Woodlands MRT station that was scheduled to complete and open on 10 February 1996, accelerated plans to relocate and develop an entirely new town centre for Woodlands New Town at Woodlands Square, the new regional centre for Woodlands or more precisely, the North region.

Fitted out with 34 bus bays, the interchange was built to handle additional bus services with the further development of Hougang new town. At that time, Hougang comprised just four neighbourhoods, with large tracts to the northwest of Upper Serangoon Road still undeveloped.
